SPIRIT FORM:
The Spirit Form is a state of mind aqquired from deep thought and concentration of the Niwa bloodline. It allows the user to fuse with a soul of their choice from their family and use its power to become stronger, faster and smarter. During this phase, their eyes turn a deep purple as a sign of the spirit manifested in their body. However, the spirit form is very draining and can be only used when the person in question is in deep trouble or has a hell of a lot of chakra to spare. However, in Mizuki's case this is particularly dangerous with the Gobi as well. If both of the chakra's fuse together it creates an effect like Rock Lee's Eight Inner Gates. It increases her power, strength and speed immensely but does leave her in a coma like state afterwards for up to a week, depending on the ammount of chakra distributed.
